Frequently asked questions

What sensor sizes can CIL281 cover?

CIL281 covers sensor formats from 1/2.3″ to 2/3″. That gives you room to use the same lens across several higher-resolution sensor families.

How much resolution does CIL281 support?

The lens is rated for 10-12MP sensors with 1.55μm pixels. That makes it a good fit when you need fisheye coverage on modern high-density imagers.

Why is the -1% F-Theta distortion spec important?

The -1% F-Theta spec means the lens keeps angular mapping very close to ideal for a fisheye. That helps when you need stable calibration, perception, or multi-camera stitching.

Is CIL281 a good low-light option?

Yes. The F/1.8 aperture passes more light than slower ultra-wide lenses, so you get shorter exposure times or lower gain in dim scenes.

What is the image circle of CIL281?

CIL281 uses a 6.4mm image circle. That is what lets it cover formats up to 2/3″.

Is CIL281 sealed for exposed environments?

Yes. The listed M12A version is IP67 rated and uses BBAR on lens 1 surface 1.

CIL281 is a high-resolution fisheye M12 lens with a 1.95mm effective focal length, a 191° field of view, and a fast F/1.8 aperture. It supports 10-12MP sensors with 1.55μm pixels and projects a 6.4mm image circle. That is the combination you buy when you need very wide coverage without giving up modern pixel density.

The distortion spec is the headline here. The lens is listed at -1% F-Theta distortion, which is unusually low for a fisheye near 190°. If your pipeline depends on calibration, perception, or scene stitching, that number matters more than a generic TV distortion figure because it tells you the angular mapping stays tight across the frame.

The lens covers formats from 1/2.3" up to 2/3", so you get room across several sensor families. The optics are glass, the housing is AL6061, and that package is a better answer than low-cost plastic fisheyes when the camera has to hold focus and alignment through temperature swings.

The total weight is 13g. The listed M12A construction is IP67 rated and uses BBAR on the first surface. For outdoor or exposed cameras, the mix of sealing, wide field, and F/1.8 throughput is usually the reason this part wins.
